Hi Guys-
I'm sort of a Supercoupe owner. I took a 91 5.0 LX and got a little silly. It's got a Powerdyne XB-1A Blower with 9# pulley (Can't run the 13# in Chicago during winter, Just NOT safe), Snow Performance Alcohol/water injection intercooling, Built AOD trans, Auburn Pro-Diff with 3:73 gears, Flowmaster exhaust, 30# injectors, Custom cold air intake, BBK 70 mm T-body, C&L 73mm MAF, and lots more.
Heres the fun part- I did everything in my power to HIDE EVERYTHING. Total sleeper.
I know this is the V6 supercoupe club but I can't find any V8 guys to talk with. Can I stay and Play for a while?

Have you had it dynoed yet? Did you do Cat Back or full exhaust?

I'd run it on a dyno with a wide band oxy sensor to make sure it's not leaning out when you put your foot into it.

Did a dyno with the old BD10 blower but that is meaningless now. Cat back only exhaust. LEAN? No. 190 LPH fuel pump and 12:1 FMU = rich under boost. Got a rich/lean gauge for safety and it is ALWAYS pegged rich when floored. Plans to lower FMU to 8:1 if car will tolerate it.

Car is a riot at stoplights. high 12's / low 13's depending on traction which seems to be my biggest problem. Going to the track in a couple weeks with the 13# pulley. Will post times.
Alcohol injection set to come on at 6# of boost.
 
ImE1, that is really trick. I like your sleeper approach and I'm sure it's a fun car. Like George said, the TCCoA is where many v8 guys are and they are a super bunch of people. They know a lot about their cars and are more than willing to share what they know and do.

Hope you have a lot of fun.
 
that's cool!

of course you are welcome here!.. i kicked around the idea of doing that myself 'cuz i was having trouble finding a decent SC but i ended up finding a clean one owner 90 SC instead.....that rocks though! , it's hard to beat the 5.0 HO engine , they are damn near bullet proof!
